Front

What is conduction in the context of thermal energy transfer?

Back

Conduction is the transfer of thermal energy through direct contact between materials, where heat flows from a warmer object to a cooler one.

Front

Describe the process of convection in heat transfer.

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases), where warmer, less dense areas rise and cooler, denser areas sink.

Front

What is the formula for calculating average speed?

Back

Average Speed = Total Distance / Total Time.

Front

How does thermal energy move between objects of different temperatures?

Back

Thermal energy always moves from a high temperature object to a lower temperature object.

What does Newton's First Law of Motion state?

Back

An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.

Front

What is inertia in the context of Newton's First Law of Motion?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the role of thermal energy in cooking?

Back

Thermal energy transfers from the heat source to the food, causing it to cook.

Front

Explain how heat transfer occurs in a refrigerator.

Back

In a refrigerator, heat is removed from the interior (warm air and items) and transferred to the external environment, primarily through conduction and convection.

Front

What is the significance of temperature difference in heat transfer?

Back

A greater temperature difference between two objects increases the rate of heat transfer between them.

What are the three main modes of heat transfer?

Back

The three main modes of heat transfer are conduction, convection, and radiation.
